It’s Sunday, Oct. 12, 2008. It’s a sunny day at the Fall
Foliage Festival in Warner, New Hampshire . It will probably be 70 degrees. The sugar maples glow orange and yellow. We haven’t
had a frost.
I’m announcing the Logging contest. Its log
rolling; cross cut sawing, under hand chopping, chain sawing, ax throwing, wood splitting. Some world champions, like Ed Brightman
and Herb Gingras, show up to compete for $50 first prizes.
It’s
the best of times. The stands are full. The contestants, from veterans, like John Postemski, who just had a knee replacement;
to the young women and men from the Thompson School at UNH entertain the crowd with feats of daring, strength, and fortitude.
We have twenty more contestants than usual. My wife Luanne and I are at the
scorers' table running two events at once so we can finish before dark. We alternate between buck sawing and wood splitting,
and then ax throw and underhand chop. A good day for everyone made possible by our group of volunteer neighbors who bring
their chain saws and heavy equipment to wrestle the competition saw bunks into place and cur and haul the pine 8x 8’s
into place.
Global climatic change has its short-term upside.
It’s not instant gloom and doom. And sure a 70 degree Oct. day has weather explanations. By itself it’s not indicative
of climate change. Unfortunately, the climate is changing. The frosts and the winter are later. We’d expect a frost
around Labor Day. Now it’s more than a month later, and still not close. October is more like September. November is
more like October.
People used to bet on the
day of ice out on the big lakes, like Winnipesaukee and Champlain. Now they may not be totally frozen over at all.
Two winters ago I kayaked on a still unfrozen Mountain View Lake at the foot of Mount Sunapee around Jan. 1.
The farther north you go, the more dramatic the changes. The Arctic Ocean
will become ice free in the summer, unleashing further warming as sunlight is no longer reflected back by the ice. Already,
methane, a much more potent green house gas than carbon dioxide, is reported bubbling from thawing permafrost into the atmosphere.
It is not only the balance sheets of banks and global finance companies that
are in disarray and threatening bankruptcy as capital assets disappear. The global climate balance sheet is sending us unmistakable
signals that we must act now before the planet is forced to find a new climate balance point, one that may not be at all favorable
for our civilization and our species.
This glorious day amidst brilliant
sun and good neighbors is also a signal to us that if we do not act responsibly we risk all of this, not just for ourselves,
but for our kids and grandkids.
We have the tools that we need to make a difference.
We can build a continental renewable power grid and create millions of jobs using wind and solar and hydro not only to replace
coal electricity, but to power electric cars that use no gasoline.
We
can replace all income taxation with ecological consumption taxes to allow the market to send proper price signals. What’s
sustainable will be cheaper. What’s polluting, depleting and ecologically damaging will be more expensive. Our hearts
tell us what we should do. Prices tell us what we will do. We can use ecological taxes to get the prices right.
We can do all these things. Now is the time for us to decide if we want to or not.

Methane released in the Arctic could raise global temperatures
By Jessica Salter

Millions
of tons of methane stored beneath the Arctic seabed is bubbling up to the surface and being released into the atmosphere as
the region warms up and the ice retreats, scientists have said.
The gas is said to be 20 times more powerful than carbon dioxide
and scientists have warned that it could accelerate global warming.
It is usually locked in a deep freeze below the sea, but as the
ice melts on the surface, small holes, or “chimneys”, appear and the gas escapes.
Orjan Gustafsson, of Stockholm
University in Sweden, who is onboard the Russian research ship Jacob Smirnitskyi, said: “Yesterday for the first time
we documented a field where the release was so intense that the methane did not have time to dissolve into the seawater but
was rising as methane bubbles to the sea surface.”
He told The Independent that the team were documenting the “methane
chimneys” using an echo sounder and seismic instruments.
Scientists believe that underground stores of methane have in the
past been responsible for rapid rises in global temperatures, changes in the climate and even extinction of species.
They think that
the amount of methane being released from the area of the Arctic along the Siberian continental shelf could equal the emissions
from the rest of the world’s oceans put together.
The preliminary findings of the International Siberian Shelf Study
2008 are being prepared for publication by the American Geophysical Union. ----------------------------------------------- |

Scrutinizing a 139-year record, a climatologist
has discovered a dramatic shift in the seasonal changes in water levels on the Great Lakes .
The finding, reported at a recent meeting of the International Association of Great
Lakes Research by climatologist John Lenters, is further evidence that the effects of global warming on natural systems could
be far-reaching.
"The bottom line is that over this
139-year period, the annual rising and falling of lakes Ontario and Erie has gotten earlier" by about a month, Lenters
said in his assessment of long-term trends in Great Lakes water levels.
The finding, Lenters said, also shows that the range of Lake Ontario 's "annual
cycle" increased from 17 to 22 inches, a change in volume equivalent to 90 billion cubic feet of water.
While Lake Erie does not show the same increase, the one-month early arrival of seasonal
high and low water levels mirrors that of Lake Ontario .
In
the Great Lakes, explained Lenters, there is an annual ebb and flow of lake levels influenced by such things as precipitation,
snowmelt and evaporation over the Great Lakes basin.
In
the spring and summer, lake levels rise, reflecting such things as precipitation and spring snowmelt. In the fall and winter,
lake levels recede as a result of evaporation of the relatively warm lake water.
These shifts, according to Lenters, are essentially hydrological representations of the seasons, and
"what I am finding is a shifting of the seasons."
These
shifts are independent of annual variability in lake levels that may reflect, for example, a drought year, or a year when
rainfall exceeds normal precipitation averages.
"At
this time, the most likely explanation for the observed trends appears to be earlier spring snowmelt in association with higher
springtime temperatures in the Great Lakes region," Lenters said. "Climate is almost definitely responsible, but
exactly how it is responsible is unknown."

Lenters' analysis was made using records of monthly mean lake levels from 1860 to 1998 from four stations around
the Great Lakes, including sites along lakes Superior, Huron, Ontario and Erie. Lake Michigan is included in the study as
part of Lake Huron since the two lakes are hydraulically connected.
Large shifts in the water cycles of lakes Superior and Michigan-Huron were also found, but for fewer months of
the year. The result is a different and less dramatic seasonal shift for those lakes, said Lenters.
"It is not clear why Lakes Superior and Michigan-Huron are behaving differently,
but it may be related to differences in regional climate, or the fact that Erie and Ontario are the furthest downstream lakes.
"If warming continues, we may begin to see the same consequences in lakes Superior
, Michigan and Huron," Lenters said. "For example, following the warm El Niño winter of 1997-1998, all five
Great Lakes reached their annual maximum nearly two months earlier than normal."
It is likely that the changes observed in the lakes are part of a larger systemic change spurred by
increased levels of carbon dioxide in the atmosphere and resulting warming trends, according to the University of Wisconsin
climatologist. Similar long-term shifts in lake ice and river flow in the Great Lakes and Upper Mississippi basins have already
been observed by scientists.
Lenters is a staff scientist
in the Climate, People and Environment Program at the university's Institute for Environmental Studies. His work was supported
by a grant from NASA's Upper Midwest Regional Earth Science Application Center.
